Nvidia research chief: AI still lacks a crucial element

In the wake of Amazon's hiring debacle involving an artificial intelligence (AI)-powered recruiter discriminating against women, experts maintain that machines themselves aren't biased -- they're only mirroring and amplifying cultural biases in the real world. The solution to shoddy machine learning, these experts say, is deceptively simple: better data. Worldwide spending on cognitive and artificial intelligence (AI) systems reached an estimated $19 billion, almost doubling the amount from 2017, according to research firm IDC. The promise of AI technology has spawned a race between the U.S. and China, both fighting for the title of global leader. According to a report by PwC, the industry is expected to boost U.S. GDP by 14.5% by 2030 -- second only to China, which is expected to see a 26.1% boost.
